•
Make sure that the condenser corresponds to the requirement of the pump (one phase).
•
Make sure that the suction through the hose works without any problem. If the suction device of
the pump should not work properly, the hydraulic elements of the pump could be damaged.
•
In case the suction line is bent/curved, a non-return valve with a sieve should be installed to the
end of the suction tube/line.
•
All connections of the suction line must be installed correctly and tightened completely.
•
Do not use anti-vibration hoses, that might impair the flow.
•
Before start, check the direction of rotation.
•
Never let the pump run dry. The pump and suction line should always be filled with water.
Operating the pump
1.
Set up the pump on a level and solid surface.
2.
Place the pump at a horizontal position to help the bearing to work properly and to fix the pump
the surface.
3.
Install the suction line so that it is ready for use. The suction hose should not be narrower than
the suction connection.
4.
Connect to mains.
5.
Fill in the pump with water at the pressure port.
6.
During the suction process, the shut-off devices (valves, spray nozzles, etc.) in the pressure
line must be completely open so that the air in the suction line can escape freely.
7.
Depending on the suction height and air quantity in the suction line, the first suction process can
take some time. With longer suction periods of sucking in, new water should be refilled.
8.
If the pump is removed after its use, do not forget that it must be refilled with water before you
operate the pump again and before restarting and connecting it again.
In case there is a water accumulation or you hear a rattling noise, the pump cannot build up the required
pressure to switch off automatically. In such case, it must be assumed that the system has not been
purged or that there is a leaking spot in the suction zone. A possible leakage can be detected as follows:
1.
Fix one end of the suction hose to a water tap.
2.
Now open the water tap and place the other end of the suction hose into another recipient filled
with water.
3.
Should you detect a spot where water and air bubbles come out, this is the leaking spot. In such
case, the device cannot work properly.
Attention!
The pump is equipped with an overheat control, but it has no safety device that switches
off the pump automatically when it runs dry.
Electric connections
The one-phase motor has been installed with a thermo-protection. With a three-phase pump, this
protection should be realised by the user.
